The COBOL tests has many tests which just dump emit lots of output
to stdout and want to compare it against expected output.
We have the dg-output directive, but if one needs more than dozens
of lines in the output, adding hundreds of dg-output directives to
each source uses too much memory and is harder to maintain.
The following patch offers an alternative, dg-output-file
directive where one can supply a text file with expected output
(no regexp matching in that case, just exact output, except that it
handles different line ending styles (for the expected file
using tcl gets, for the actual output skips over \n, \r\n or \r).
And a newline at the end of the whole output is optional (in the actual
output, because I think some boards get it eaten).
Also tested with addition or subtraction of some characters from the
expected output files and saw FAILs with appropriate messages.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
